...HIGH SURF WARNING FOR NORTH AND WEST FACING SHORES OF NIIHAU
KAUAI OAHU MOLOKAI AND NORTH FACING SHORES OF MAUI...
.Surf along exposed north and west facing shores will rapidly
build overnight, peak Thursday afternoon through Friday, then slowly
ease over the weekend as a significant west-northwest (290 to 315
degrees) swell builds down the island chain. The High Surf Warning has
been issued for exposed north and west facing shores of the smaller
islands this evening, but will need to be expanded with at least an
advisory for the west facing shores of the Big Island early
Thursday.
* WHAT...Surf of 18 to 25 feet, building to 20 to 30 feet Thursday
afternoon along north facing shores of Niihau, Kauai, Oahu,
Molokai and Maui. Surf of 15 to 20 feet, building to 18 to 22
feet by noon on Thursday along west facing shores of Niihau,
Kauai, Oahu, and Molokai.
* WHERE...North and west facing shores of Niihau, Kauai, Oahu, and
Molokai, and north facing shores of Maui.
* WHEN...From midnight tonight to 6 AM HST Friday.
* IMPACTS...Very High...Expect ocean water surging and sweeping
across beaches, coastal benches, and lava flows creating the
potential for impacts to coastal properties and infrastructure,
including roadways. Powerful longshore and rip currents will be
present at most beaches. Large breaking waves and strong
currents may impact harbor entrances and channels causing
challenging boat handling.
Stay away from the shoreline along the affected coasts. Be
prepared for road closures. Postpone entering or leaving channels
affected by the high surf until the surf subsides.
